 \hline\hline \end{tabular*} {\centering \caption*{\begin{footnotesize} \textit{Notes:} This table checks robustness of our baseline event study estimates in Table \ref{tab:es1} by changing event definitions. Columns 1-3 report estimates for MSCZ pairs, while Columns 4-6 have results for BC pairs. Columns 1 and 4 include federal increase events, as discussed in sub-section \ref{sec:app_fed_inc}. Columns 2 and 5 remove events that have a federal increase up to three years prior. Finally, Columns 3 and 6 use the uncombined event definitions from \cite{cengiz2019effect}, also using their specification to control for other events in the event window (see sub-section \ref{sec:app_CDLZ_events}). Outcomes are defined similarly to Table \ref{tab:es1}. Standard errors, reported in parentheses, are clustered at the state level. Stars indicate statistical significance as follows: \sym{*} \(p<0.10\), \sym{**} \(p<0.05\), \sym{***} \(p<0.01\) \end{footnotesize}}} \end{table}
